The talk will focus on the testability prospects of the minimal type-I seesaw model to generate the light neutrino masses and the associated mechanism generating the observed baryon asymmetry.
We will see how CP invariants emerge in the analytical solutions of the quantum kinetic equations, which will, in turn, reveal previously undiscovered correlations among various observables.
For non-degenerate right-handed neutrinos, a significant modification of the neutrinoless double-beta decay rate is anticipated compared to that of active neutrinos, at reach of current and future experiments, and a highly constrained flavor structure for the mixing with the active neutrinos. On the other hand, for degenerate right-handed neutrinos, we will see how light neutrino oscillations and collider experiments are sufficient to fully predict both the baryon asymmetry and the amplitude of neutrinoless double-beta decay.
